Organic UV Invisible Fluorescent Pigment for Security Printing on Identification

UV invisible pigment is a special type of pigment that may appear normal or light in color under normal light, but emits very bright and vivid visible light when exposed to ultraviolet (UV) light. During this process, the pigment absorbs the invisible ultraviolet light energy and converts it into visible light with a longer wavelength for emission. This process is real-time. Once the UV light source is removed, the luminescence usually stops immediately. Under UV light, the light intensity emitted by fluorescent pigments is much higher than that reflected by ordinary pigments. The colors are extremely bright, saturated and dazzling, with a strong visual impact.

UV invisible Pigments are widely used in:

Currency and important documents:
Banknotes, passports, ID cards, bank cards, etc. are often embedded with fluorescent fibers, patterns or inks, which display specific fluorescent marks under a currency detector (UV lamp) for anti-counterfeiting verification.

Anti-counterfeiting labels:
Special fluorescent patterns or codes are used on the packaging, labels and seals of brand products to prevent counterfeiting.
